BRUSSELS, BELGIUM (CNN) – German Chancellor Angela Merkel says trust between Europe and the U.S. must be “reestablished.”

This, after claims the U.S. National Security agency eavesdropped on her cell phone.

Merkel made the comment as she arrived at a summit of European Union leaders in Brussels, Belgium.

The summit risks being overshadowed by anger over allegations the U.S. has been spying on its allies.

"I would like to also touch on the matter of the allegations regarding the NSA,” Merkel said. “There needs to be trust between the U.S. and European nations and that eavesdropping amongst friends in never acceptable no matter in what situation. As I said it back in June in Berlin, and again reiterated yesterday in a phone call with the president (Obama). This issue doesn't affect just me but in the interest of all German citizens. Now, we have to discuss what sort of data-protection do we need and what sort transparency there is. We are closely tied in with the U.S., and trust is an important part of the relationship and now that trust has to be re-established between us. Spying among friends is never acceptable."

The White House says President Obama told Merkel Wednesday that the U.S. “is not monitoring and will not monitor” her communications.

Meanwhile, France is angry over allegations that the NSA intercepted millions of phone calls there. A French newspaper reported claims that the NSA intercepted more than 70 million phone calls in France over a 30-day period.

U.S. Director of National Intelligence, James Clapper, says the report contains “inaccurate and misleading information regarding U.S. foreign intelligence agencies.”
